GAGE FOR SHERS.

SPECIFICATION formingjpart of Letters Patent No. 663,652, dated December11, 1900.

Application filed May 4, 1900. Serial No. 15,504. (No model.)

T0 @ZZ whom it may concern.:

Be it known that I, CHARLES DW. COLBY, a citizen of the United States,residing at Albion, in the county of Calhoun and State of Michigan, haveinvented cert-ain new and usefnlImprovements in Shears-Gages; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

My invention relates to improvements in shears-gages; and itconsists inthe novel features of construction hereinafter described, referenceheilig had to the accompanying drawings, which illustrate one form inwhich I have contemplated embodying my invention, and said invention isfully disclosed in the following description and claims.

Referring to the drawings, Figure l shows my im proved gage applied to apair of shears. Fig. 2 is a perspective view of the attaching device anda portion of the frame.

The object of my invention is to provide an im proved gage or guide tobe applied to shears for cutting uniform widths of silk or other fabric.

Myimproved shearsgage consists of a piece of stout wire or othersuitable material bent so as to form a long narrow guide-frame K K II G.On the long sides K K is secured the gage-plate L, of tin or othersuitable material, having a bent-up edge guide M thereon. The gage-plateL, being adjustable on the long sides K K', may be moved along the sameto any desired position for the purpose of cutting different widths. Thecontinuation of the' end piece G of the frame above referred tois'welded to the bent portion E of the side piece K', as shown in Fig.2, and angles are formed in the two wires, as at N, in order to preventthe blades of the shears from coming in Contact with the saidguide-frame.

At a sui-table distance from the guide-frame the wire G is bent in theform of a clamp, as shown at I, adapted to be fastened onto the stem a.'of the thumb-piece A of the shears.

Sleeves .I and F may be provided to encircle the welded portions of thetwo wires G E on either side of the clamp I, so as to prevent theirbeing pulled apart by the strain on the clamp. The other wire E isformed into a large loop C, which substantially coincides with thethumb-piece A, and is provided on its forward end with a spring-hook D,adapted to engage the forward portion ctof said thumbpiece.

The vertical plane of the loop C is parallel with the edge guide of thegage-plate L.

The application of my invention to a pair of shears is as follows: Theclamp I engages the stem of the thumb-piece, the spring-hook D isfastened to the forward portion of said thumb-piece,and the gage-plateset at a given distance from the cutting edge equivalent to the width tobe cut, when it is obvious that the said widths will be uniformthroughout.

What I claim, and desire to secure by Letters Patent, is-

I. A gage for shears consisting of a gageplate, an edge guide on saidplate, a frame adapted to serve as a guide for said plate, a clampadapted to engage the stem of the thumb-piece of the shears, a loopformed on said frame and a spring-hook provided on said loop for securing said loop to said thumbpiece.

2. A gage for shears consisting of a gageplate, an edge guide on saidplate, aframe adapted to serve as a guide for said plate, adownwardly-extending spring-clamp adapted to engage the stem of thethumb-piece of said shears, and a loop adapted to coincide with said thunnb-piece and provided with a hook to engage said thumb-piece,substantially as described.

In testimony whereof I affix my signature in the presence of twowitnesses.

CHARLES D. IV. COLBY.
